Abstract
Background
Non-alcoholic fatty liver disease (NAFLD) is a common, severe disease in obese patients. However, NAFLD is usually underestimated by ultrasonography. Liver biopsy is not routinely done in bariatric surgery or during the follow-up. This study therefore examined the correlation between metabolic syndrome and NAFLD in morbidly obese patients based on an assessment using transient hepatic elastography (THE).
Material and Methods
This study involved 50 female patients in the pre-operative phase for bariatric surgery. Before surgery, we collected clinical, laboratory, and anthropometric variables. THE measurements were obtained using a FibroScan® device (Echosens, Paris, France), and steatosis was quantified using Controlled Attenuation Parameter software (CAP). Statistical analyses were done using linear correlation and the Kruskal-Wallis test.
Results
The mean of THE and CAP values were 7.56 ± 4.78 kPa and 279.94 ± 45.69 dB/m, respectively, and there was a significant linear correlation between the two measurements (r = 0.651; p < 0.001). The numbers of metabolic syndrome parameters did not influence the THE (p = 0.436) or CAP (p = 0.422) values. HbA1c and HOMA-IR showed a strong linear correlation with CAP (r = 0.643, p = 0.013 and r = 0.668, p = 0.009, respectively) and a tendency to some linear correlation with THE (r = 0.500, p = 0.05 and r = 0.500, p = 0.002, respectively).
Conclusion
Morbidly obese women submitted to FibroScan® presented a high prevalence of severe steatosis and advanced fibrosis in our sample. Insulin resistance parameters were correlated with steatosis, but less with fibrosis.
